The Health and Human Services Department makes more than half of the improper payments reported across the entire federal government. Last year, it handed out $65 billion that it shouldn’t have.

Kay Daly is the assistant inspector general for audit services at HHS. It’s her task to review these wrong payments each year.

Federal News Radio spoke to Daly as part of our special report, Rise of the Money People. The Federal Drive’s Tom Temin and Emily Kopp asked her why HHS has such a problem with improper payments and what’s being done to address the problem.
